Why it works: Pepper and parsley match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓
White Fricassee of Chicken
Ingredients
Directions
Cook the chicken
Cover the chicken pieces with boiling water in a kettle.
Simmer slowly until tender, leaving the cover half off to reduce the gravy.
Season with salt and pepper.
Lift out the chicken and place it on a platter on toasted bread.
Make the gravy
In a frying pan, heat the butter.
Stir in the flour and cook slowly for 2-3 minutes, stirring constantly.
Remove from heat and gradually add the milk, mixing well.
Pour the mixture back into the kettle and bring to a boil.
Add more salt and pepper if needed.
Let the gravy boil for 2-3 minutes.
Remove from heat and stir in the beaten egg yolks.
Serve
Pour the gravy over the chicken and toast.
Sprinkle with chopped parsley before serving.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Chicken
- Provides the main protein, which becomes tender through slow simmering in the water.
- Butter
- Fat that carries the flavour and, with the flour, forms the base of the roux.
- Flour
- Thickens the gravy when cooked in butter and combined with the milk.
- Milk
- Liquid that, with the flour roux, becomes the creamy body of the gravy.
- Egg yolks
- Enrich and thicken the gravy, adding richness and a smooth texture.
The step that matters
Stirring in the egg yolks off the heat. Egg yolks can curdle and turn grainy if they overheat, so they are added after the gravy comes off the heat to keep it smooth.
Swap the parsley
How well each one fits the dish's main ingredients (chicken, pepper, butter, flour, milk, egg):
- Nutmegfits about as well
- Parsleythe original
- Cinnamonfits about as well
- Tarragonfits about as well
Fit is the average pairing score against chicken, pepper, butter, flour, milk, egg. Candidates are from the same food group and used in at least 100 recipes.
